there's always more to the truth!
Another fact that website fails to note is the large number of European pilots and planes that DO fly intra-Europe for UPS. Star Airlines flies TEN B767 freighters intra-Europe under contract to UPS, and MNG also flies several routes for UPS.
I'm a pilot for UPS, and I do not fly, nor endorse cabotage. The bilateral agreements made between our individual governments determines the level of service I can provide on all the international routes I fly. Cabotage is not allowed under any of those agreements. That's why UPS has so many EU contractors supplementing our CGN operation.
I would not be surprised to find that a majority of the intra-Europe UPS volume IS flown by EU pilots. Plus, a LOT of international volume (everything from Africa, S America, Russia) comes to the EU via belly freight on passenger jets for distribution via our air and ground networks.
